EDGE-TRDDIER.

To all whom it may concern.

Be it known that I, WILLLm M. Bons- MNG, a citizen of the United States, and resident of Manitowoc, in the county' of Manitowoc and State of Wisconsin, have in vented certain new and useful Improvements in Edge-Trimmers; and I do hereby iefollowing is a full, clear, and exact description thereof.

The object of my invention is to provide a. simple, effective and durable planing machine-especially adapted to trimming the edges of wood-veneer blanks, said trimming being a necessary step in the process of veneer manufacture for the purpose of obtaining a perfect edged unitary joint preparatory to abutting the edges of the blanks together and thereafter gluing the same, the construction and arrangement of the mechanism of the machine being such that the veneer blanks or strips are securely clamped one upon the other, between endless travel ing carriers and feed past revoluble cutterheads, which cutter-heads true and smooth the veneer edges.

The invention therefore consists in various peculiarities of construction and combination of parts as hereinafter fully described with reference to the accompanying drawings and subsequently claimed.

in the drawings: Figure 1 represents a side elevation of .a machine embodying the features of my invention, parts being broken away and parts in section to better illustrate the details of construction; Fig. 2, a plan view of the same partly broken away and in section, as indicatcd'by line 2'2 of Fig. 1; Fig; 3, an enlarged. detail sectional elevation of the. feed-mechanism, the section being indicated. by line 3-3 of Fig. 2, and Figs. 4 and 5, are enlarged cross-sections of the respectively of'l ig. 1.

Referring by letter to the drawings, A 'indie-ates a table supported by legs B, B and provided with front. and rearbearings for carry an endless driven link-belt X. The link-belt rec ives its drive from a counter shaft E, which counter shaft is mounted in suitable hearings on the rear table legs B Specification of Letters Patent;

, The sprocket-wheels D, D are locat Lv beneath the table in such a'position that;.=tl 1e work-engaging run of the link helt projects slightly above the top of said table,

These side-strips togetherwiththe rollers form a separableondetachable guide which is fitted into the trough Fto prevent The side-strip 9} projects upward flush with the table-top, while the opposite stri g is 'cutlawaytdpermit a. gagesstrip H to e snugly fitted agaihstthe adjacent ribbed portions of the fbelt-links, the .opposite parallel rib-portions being in contact with the inner face of the side-strip all of which construction is best shown in Fig. 4 of the drawings. 7 j

- Provision is made for adjusting the gagestrip by means of. set-screws h, having their heads abutting the wall of a channel Iin the table-top, the shank's of the set-screws'being in threaded-connection w'th said guide stripJ The aforesaid guide-stri is fitted'ihtofthe channel flush with the ta le-top, andsecured to the table by screws 4., the shanks of which screws pass through shouldered slots in the guide-strip, while the heads of's'aid screws are sunk therein, the slots permitting. movement of the aforesaid guide-stri when the screws are loosened to accomplis the-adjustment.

lificated above the table-top is another driven link-belt X similar'to that previously described, the lower or work-en ing run of which belt is disposed directly a ov the up er or work-enga ing run of thellow'er linklt X, the twoilink-belts ,beirigtdrirrlan in opposite directions and at the same speed, so that their respectivework-engaging runs will travel together and in the;- same direction, thereby practicallyformingia vise between the opposite corrugated faces of the links for the purpose of grippin lengths of veneerstrips and feeding the e 'es of the same past cutter-heads J J, to be hereafter described. I

-mounted upon a stud j secured in a forked extension of a resser-frame N, whichframe is suspended directly above the work-engaging run of said link-belt intermediate of its sprocket-wheel, by standards N -fast to the table. The 'pressef-fmrne isjformed with a lmigitudinal'rectangular channel, into which isnested a series of independently yieldin housings k, which carry anti iriction roller arranged to impinge against the ribs of the adjacent belt-links and thus form a backing forrthe work-engaging run of the link-belt. These housings have shanl'r-extensions m which project into sockets of the channelroof, between which roof and the base of the encircle the she thehousings, between which the anti- 'ction.

housings are inter osed coiled springs n that extensions. Win s o of rollers l are located, depend below said rollers and form 'uides for the belt-links, the ribs of which links fit snugly therebetween, there being apertured lugs 11 extending from the wings into. which are secured the pintlesof the anti-friction rollers. The housings 7c are fitted between side-walls O of the presserframe and are vertically guided therein by their lugs p, which lugs project through slots q of said walls, thus together with the socketed shank-extensions permitting free vertical motion to the said housings together with the rollers.

From the foregoing description it will be understood that should strips of veneer be inserted between the corrugated face of the pair of link-belts constituting the feedmechanism, the said veneer would be firmly clamped therebetween, pressure being exerted from above by the spring-controlled antifriction rollers, u on the work-enga ing run of the upper lin belt, and resisted by the links of the work-engaging run of'the lower link-belt, the last named links beingbacked up by the rollers G over which they travel as reviously stated.

n order that the tension or initial p'res sure exerted upon material .beingfed may. be regulatedlin accordance with 1ts thickmiss, the resser-frame N is arranged to be vertically adjusted upon its su'pportin standards N, said adjustment beingattalne by means of bolts 1', which bolts project from said presser-frame and are-fitted into slots 8 of the standards, to which they are secured b means of clamping nuts. The upper en of's'aid standard being formed with hubs in each of which is revolubly mounted a threaded-spindle P. The lower ends of these spindles are in threaded-con nection with lugs t of the p)resser-frame, the upper ends of said spindles eing squared for the rece tion of a suitable tool by which to raise an lower said-presser-frame, after which operation the nuts of bolts r are securely 'set to bind the partstogether. When the .presserframe isadjusted, the slack of the endless link-belt is regulated by movin the idle sprocket-wheel K in or out in its forked extension, which extension is provided with slotted openings u for the reception of the stud 1', there being eyebolts 'v'fitted over said stud having threaded ends adapted to pass through apertured ears w rejecting from the forked extensions and he d in adjusted position therewith by means of lock-nuts w. Thus it willbe seen that the idle sprocket-wheel rises or falls with the resser-frame, while, the driving sprocket-w eel Kremainsin its fixed osition with relation to the table and its 'vinggears, both sprocket-wheels being at a sufficient height from the table-top to permit the work engaging run of the link-belt to form a flared throat with relation to the work engaging run of the lower belt,.whereby the material to be edged may readily be inserted therebetween and discharged from the rear of the driving sprocket-wheels upon the table.

A supporting-rail Q for' the slack-side of the link-belt X is secured to the presserframe by braces :13, and the front or feed-end of the table is provided with an adjustable gage it against which the stock or veneer edges are abutted and guided to thegripping faces of the link-belts.

Each of the vertical cutter-heads J, J has its spindle mounted in a double bracket S which bracket is adjustably secured to the table, the latter bein slotted to permit passage of thespindles thcrcthrough. The first or roughing cutter-head J is adjusted a shade fartner from the edge of the links of the cutter-he ad J, so that the two will gradual y reduce the s 0. outer face, supporting rollers 1n the tablelnst named driven and idle sproclrct-whccls,
